Using Quantile Regression To Estimate Capital Buffer Requirements For Japanese Banks, David Allen, Robert Powell, Abhay Singh Jan 2010

Using Quantile Regression To Estimate Capital Buffer Requirements For Japanese Banks, David Allen, Robert Powell, Abhay Singh

Research outputs pre 2011

This paper investigates the impact of extreme fluctuations in bank asset values on the capital adequacy and default probabilities (PD) of Japanese Banks. We apply quantile regression analysis to the Merton structural credit model to measure how capital adequacy and PDs fluctuate over a 10 year period incorporating the Global Financial Crisis (GFC). Quantile regressions allow modelling of the extreme quantiles of a distribution, as opposed to focussing on the mean, which allows measurement of capital and PDs at the most extreme points of an economic downturn. Understanding extreme risk is essential, as it is during these extreme circumstances when …

In The Line Of Fire: The Challenges Of Managing Tourism Pperations In The Victorian Alps, Dale Sanders, Jennifer Laing Jan 2010

In The Line Of Fire: The Challenges Of Managing Tourism Pperations In The Victorian Alps, Dale Sanders, Jennifer Laing

Research outputs pre 2011

Understanding the impact of bushfires on tourism operations in Australian national parks and regional communities is of growing importance, with evidence of their increased frequency and severity linked, in part, to climate change. This is particularly critical for Australian alpine regions, given their greater emphasis on the summer season in the wake of lighter winter snowfalls. This article focuses on management issues and challenges of maintaining tourist operations within the Victorian Alps post-bushfire, including operator reactions to the bushfires and their subsequent implementation (or not) of crisis management and disaster recovery strategies. It is based on a qualitative study involving …

Revisiting The 1997 Asian Financial Crisis: A Copula Approach, A. Tsui, Zhaoyong Zhang

Research outputs pre 2011

This study is motivated by the stylized fact that the asymmetry in dependence usually exists in returns of financial data series. Owing to political and monetary reasons, this phenomenon may be present in daily changes of exchange rates. In this paper, we study the relationships between five currencies in Asia around the period of Asian Financial Crisis in 1997, including the Singapore Dollar, Japanese Yen, South Korea Won, Thailand Baht and Indonesia Rupiah. We employ various time-varying copula models to examine the possible structural breaks. The results indicate significant changes at the dependence level, tail behavior and asymmetry structures between …

Multi-Wavelength Laser Scanning Architecture For Object Discrimination, Kavitha Venkataraayan, Sreten Askraba, Kamal Alameh, Clifton Smith Jan 2010

Multi-Wavelength Laser Scanning Architecture For Object Discrimination, Kavitha Venkataraayan, Sreten Askraba, Kamal Alameh, Clifton Smith

Research outputs pre 2011

A novel method for identifying and discriminating various objects using five different lasers is described. This method uses a laser combination module that allows five laser diodes of different wavelengths to sequentially emit identically polarized light beams through a common aperture, along one optical path. Each laser beam enters a custom-made curved optical cavity for multi-beam spot generation through internal partial beam reflection. The intensity of the reflected light beams from each spot is detected by a high-speed area scan image sensor. Object discrimination based on analyzing the Gaussian profile of reflected laser light at distinguishing wavelengths is demonstrated.

Photonic-Based Multi-Wavelength Sensor For Object Identification, Kavitha Venkataraayan, Sreten Askraba, Kamal Alameh, John Rowe Jan 2010

Photonic-Based Multi-Wavelength Sensor For Object Identification, Kavitha Venkataraayan, Sreten Askraba, Kamal Alameh, John Rowe

Research outputs pre 2011

A Photonic-based multi-wavelength sensor capable of discriminating objects is proposed and demonstrated for intruder detection and identification. The sensor uses a laser combination module for input wavelength signal multiplexing and beam overlapping, a custom-made curved optical cavity for multi-beam spot generation through internal beam reflection and transmission and a high-speed imager for scattered reflectance spectral measurements. Experimental results show that five different wavelengths, namely 473nm, 532nm, 635nm, 670nm and 785nm, are necessary for discriminating various intruding objects of interest through spectral reflectance and slope measurements. Objects selected for experiments were brick, cement sheet, cotton, leather and roof tile.

Evolving Group Strategies For Ipd, Philip Hingston Jan 2010

Evolving Group Strategies For Ipd, Philip Hingston

Research outputs pre 2011

The Iterated Prisoners Dilemma (IPD) is often used to model cooperation between self-interested agents. In an earlier study, we introduced a framework using IPD to study the effects of species-level competition on the evolution of cooperative behaviour. In this paper, we extend the previous work, using co-evolutionary simulations of interactions between species of IPD-playing agents to investigate how group strategies may evolve. We find that the ability to cooperate more with agents of the same species greatly increases the ferocity of competition between species.

Pax3 Expression In Normal Skin Melanocytes And Melanocytic Lesions (Naevi And Melanomas), Sandra Medic, Mel Ziman Jan 2010

Pax3 Expression In Normal Skin Melanocytes And Melanocytic Lesions (Naevi And Melanomas), Sandra Medic, Mel Ziman

Research outputs pre 2011

Background Cutaneous Malignant Melanoma is an aggressive form of skin cancer, arising in cutaneous melanocytes. The transcription factor PAX3 regulates melanocyte specification from neural crest cells during development but expression in differentiated melanocytes is uncertain. By contrast it is frequently found in melanomas and naevi and is a marker for melanoma staging and detection. In this study we analysed the expression of PAX3 across the spectrum of melanocytic cells, from normal melanocytes to cells of benign and malignant lesions to better assess its function in these various tissues. Pax3 and PAX3 (italicized) refer to the mouse and human gene, respectively; …

Work-Family Conflict In Work Groups: Social Information Processing, Support, And Demographic Dissimilarity, Devasheesh P. Bhave, Amit Kramer, Theresa G. Glomb Jan 2010

Work-Family Conflict In Work Groups: Social Information Processing, Support, And Demographic Dissimilarity, Devasheesh P. Bhave, Amit Kramer, Theresa G. Glomb

Research Collection Lee Kong Chian School Of Business

We used social information processing theory to examine the effect of work-family conflict (WFC) at the work group level on individuals' experience of WFC. Consistent with hypotheses, results suggest that WFC at the work group level influences individual WFC over and above the shared work environment and job demands. It was also observed that work group support and demographic dissimilarity moderate this relationship. Moderator analyses suggest that work group social support buffers WFC for individuals but is also associated with a stronger effect of work group WFC on individuals' WFC. Moreover, the work group effect on individuals' WFC was shown …

Impactful Management Research: The Importance Of Finding The Voice Of Practice In Management Research, Howard Thomas Jan 2010

Impactful Management Research: The Importance Of Finding The Voice Of Practice In Management Research, Howard Thomas

Research Collection Lee Kong Chian School Of Business

Management research in business schools faces increasing internal and external criticism for the production of rigorous and theoretically grounded but irrelevant research (Mintzberg, 2004; Pfeffer, 2007). This criticism is compounded by often unfavourable comparisons between the academic stature of business schools relative to other professional schools (e.g. medicine, law and engineering) (Bennis and O'Toole, 2005; Khurana, 2007) and to the university communities which they reside (Starkey and Tiratsoo, 2007).

The Employment Relationship, John W. Budd, Devasheesh P. Bhave Jan 2010

The Employment Relationship, John W. Budd, Devasheesh P. Bhave

Research Collection Lee Kong Chian School Of Business

The employment relationship is the connection between employees and employers through which individuals sell their labor. This might consist of an immigrant day laborer paid by the bushel to pick fruit in the hot sun, a salaried manager who has been working in an air-conditioned office for the same company for 40 years, or innumerable other situations. Irrespective of situation, all employees and employers have fundamental interests they pursue through the employment relationship, all forms of this relationship are mediated by labor markets and states, and each instance of this relationship is governed by some form of a contract, ranging …

Boldness And Reproductive Fitness Correlates In The Eastern Mosquitofish,Gambusia Holbrooki, Alexander D.M. Wilson, Jean Guy J. Godin, Ashley J.W. Ward Jan 2010

Boldness And Reproductive Fitness Correlates In The Eastern Mosquitofish,Gambusia Holbrooki, Alexander D.M. Wilson, Jean Guy J. Godin, Ashley J.W. Ward

School of Biological and Marine Sciences

AbstractAnimals are known to exhibit ‘personality’; that is, individual differences in behaviour that are consistent across time and/or situations. One axis of personality of particular importance for behavioural ecology is boldness, which can be defined as the tendency of an individual to take risks. The relationship between individual personality and fitness correlates, particularly those involved in reproduction, remains largely unexplored. In the current study, we used female Eastern mosquitofish (Gambusia holbrooki) to ascertain whether certain reproductive traits (e.g. stage of pregnancy, fecundity) are correlated with individual personality in two wild populations in New South Wales, Australia. To quantitatively assess this …

Long-Term Earnings Growth Forecasts, Limited Attention, And Return Predictability, Zhi Da, Mitchell Craig Warachka Jan 2010

Long-Term Earnings Growth Forecasts, Limited Attention, And Return Predictability, Zhi Da, Mitchell Craig Warachka

Research Collection Lee Kong Chian School Of Business

Long-term earnings expectations are critically important to stock price valuations. We identify relative optimism and relative pessimism in long-term analyst forecasts by comparing these forecasts with implied short-term earnings growth forecasts across rms within the same industry. Stocks with relatively optimistic and relatively pessimistic long-term analyst forecasts have negative and positive risk-adjusted returns, respectively. This return predictability depends critically on short-term forecasts since relative optimism and relative pessimism originate from the slow diffusion of information from short-term to long-term analyst forecasts. Our results indicate that market participants have limited attention regarding the long-term earnings implications of information.

Is Regime Switching In Stock Returns Important In Asset Allocations?, Jun Tu Jan 2010

Is Regime Switching In Stock Returns Important In Asset Allocations?, Jun Tu

Research Collection Lee Kong Chian School Of Business

The stock market displays regime switching between upturns and downturns. This paper provides a Bayesian framework for making portfolio decisions that takes this regime switching into account, together with asset pricing model uncertainty and parameter uncertainty. The findings reveal that the economic value of accounting for regimes is substantially independent of whether or not model and parameter uncertainties are incorporated: the certainty-equivalent losses associated with ignoring regime switching are generally above 2% per year, and can be as high as 10%. These results suggest that the more realistic regime switching model is fundamentally different from the commonly used single-state model, …
